We demonstrate an effective strategy for capture and conversion of H2S in novel superbase protic ionic liquids (SPILs). It is found that the synthesized SPILs with the multiple active sites exhibit the unprecedented H2S uptake via chemical absorption (up to 1.81 mol mol−1 at 298.2 K and 1 bar). More importantly, H2S molecule is activated by these SPILs during the absorption process, so that the activated...
In view of the environmental hazards caused by SO2, the development of efficient SO2 capture technology has important practical significance. In this work, a low‐viscosity protic ionic liquids containing imidazole (Im), ether linkage, and tertiary amine structure was synthesized by acid–base neutralization of tris(3,6‐dioxaheptyl)amine (TMEA) and Im for SO2 absorption. The results showed that the...
